And here's the Sojurner out of it's box!

Side view of the Sojurner.

Please note the gears (total of two) between each of the wheels. These are how the single motor drives all the wheels on each side.

Also note the assortment of levers connecting the wheels to the body. This allows the wheels on the left of the picture to pivot up and down as the Sojurner goes over obstacles.

The undercarriage. The gear box for the motor is underneath the panel on the left side of the picture.

The "Solar Panel" has been removed. Note the 4 AA nicad batteries on the upper left portion of the Sojurner.

Top view of the Sojurner with the "Solar Panel", batteries, and the electronics cover removed. The red you see in the middle is the radio antenna, and the board you see is the electronics for the radio.

Same view as above, but with the battery compartment removed.

[eric/robots/toys/sojurner/mars_b_5.jpg]
This is the undercarriage of the Sojurner with the motor compartment panel removed. Note that there is only one motor for the Sojurner, and there is no cam assembly in place to make it turn in reverse. ( Rats!!!)

[eric/robots/toys/sojurner/mars_b_6.jpg]
Same picture as above, but with two standard Airtronics servos in place. Please note that these servos Do NOT fit inside the motor compartment. It is possible that two wing servos might fit in the compartment, but even so, it is probable that re-installing the cover would be impossible.
